Okay, so as every person who’s ever seen a single post of mine knows, I play roleplaying games.
I’m working on a game I’m running now - and want to provide pseudoscientific backgrounds for the principles of Time Travel, and Dimensional Travel.
So, first, we must envision the universe as a timeline, stretching out to infinity. And Imagine the parallel universes, branching off from the main universe at different point, creating something that, viewed externally, quite resembles a tree.
The “null” space between timelines is the 5th dimension, “Trans-time.”
This becomes important in a second. The first method for “time travel” the scientists of the campaign will discover will be based on the “principle” of gravitic induction. (Yes, it’s time for technobabble.) Essentially - gravity warps spacetime. A singularity like a Black Hole can warp it to an extreme degree. If one wishes to travel in time, then a small ring of small black holes is required - or something that generates an equivalent gravitic force - a force intense enough to “peel back” the skin of space-time at the center of the ring - the more gravity you have, the farther back you can peel the skin.
Now, the ability to travel to a parallel dimension is much easier to come by. It relies on a similar notion - except instead of gravity, which scientists haven’t learned to manipulate so well, it requires magnetic fields. Essentially, it is discovered that a powerful magnetic field produces a small vector in the fifth-dimensional direction. It warps the trans-time barrier around a universe in a small way. By increasing the intensity of the field, that vector grows larger - the warp grows more pronounced, until finally, the barrier bursts, creating a ‘wormhole’ through which one could ‘slide’ into the parallel world. Perhaps one with no shrimp. Or nothing but shrimp.
Of course, these wouldn’t need to be the only ways to achieve these effects, just the first that the scientists of the campaign discover.
So how’s my pseudoscience?
